EDIVARD LESLIE, OF ORANGEVILLE, ONTARIO, CANADA.

CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 405,040, dated June 11, 1889.

Application filed June 18, 1888. Serial No. 277,437. (No model.)

To all whom it may concern:

Be it known that I, EDWARD LESLIE, of

'Orangeville, county of Dutferin, Province of improved car-axle bearing adapted for the standard-box, and in which the angular motion of the axle is allowed for, while at the same time a narrow bearing-brass can be used, which is properly supported at the upper part. The accompanying drawings represent the parts as follows:

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is a sectional end view of the same on the line a: so of Fig. 1. Fig. 3 is a sectional plan view of the same on the line y g of Fig. 1. Fig. 4 is a plan view of the keeper. Fig. 5 is a side elevation of the same. Fig. 6 is a sectional side elevation of the same. Fig. 7 is an inverted plan view of the same. Fig. 8 is a plan flew of the axlebrass, and Fig. 9 is a side elevation of the same.

The car-axle A projects with its journaled ends A into the car-axle box 13, which box is of the usual standard type. The box B is provided on the under side of the stop with stops D and on the inner circle of its side with stops E. In between the stops is fitted a flat key F, abutting at its front end against the stops D, and provided on each side with alug F, abutting against the front of the In the center of the key F is formed an aperture F into which is fitted a hub or boss G projecting from the top of the intermediate plate G. The intermediate plate G, besides being provided with ahub G, is also provided with two downwardly-extending side flanges G G and between these flanges, and parallel with the line of the axle, is formed a semi-cylindrical recess, as is shown in Fig. 1. This semi-cylindrical recess is a part of the cylinder, the axis of which lies at right angles with the journal of the axle. This curved recess is indicated in the drawings by the letter G The axle-brass H is provided on the lower side with a suitable semi-cylindrical recess to fit the axle, and on its upper side it is provided with a semi-cylindrical convex proj eetion that fits the curved recess in the intermediate plate G. In this way, when the axle moves so'as to change its angle vertically in the box, the brass H can turn on the plate G, the two semicylindrical surfaces permitting this movement, and when the axle moves in the box and its angle horizontally is changed the intermediate plate Gcan turn in the key-which is fastened and held in the top of the box. I purposely make the brass H narrow and provide two downwardly-projecting side flanges G Giwhich hold the brass and force it in turnin ghoriz'ontally to carry with it the plate G. In

this way I can make a narrow brass and support it firmly by the plate G.

In the middle of the axle-brass H is formed vertically a conical aperture H which permits the oil to pass from the journal A to the bearing-surfaces G and H of the keeper G and the axle-brass H, respectively. A small cylindrical aperture G is formed in the middle of the keeper G, passing through the center of the offset G, and serving to deliver oil from the aperture H to the offset G and its seat in the key F.

I am aware of the patent granted to Baker, No. 370,034, also patent of B. A. Hopkins, No. 216,517. In thepatent oi Baker a hemispherical projection is made from the brass, which slips into a like indentation in an intermediate plate, while in the patent of- Hopkins a short semi-cylindrical bearing is formed. Now my invention resides in forming on the upper part of the intermediate plate G a hub which penetrates the key, so that the movement of the axle in horizontal angles may be allowed for, and in providing said intermediate plate with flanges, as before described, sothat the narrow brasses which are used will be held firmly within the flanges and be caused to move in horizontal angles with the plate as a single piece, while at the same time any movement in vertical angle will be allowed for by reason of the semi-cylindrical bearing formed between the brass and intermediate plate. In the earlier patents this arrangement is not found, for in Hopkins and Baker-the brass is practically the full width of the box, and in cases where a narrow brass has been employed the brass has not been held between downwardlyprojecting flanges forming part of and inter mediate plate placed between the key and the brass. It will be seen that the horizontal movements are all allowed for by the movement of the intermediate plate, while all vertical movements are allowed for between the brass and the intermediate plate.

I have found from the particular construction of my bearing that I get as much surface from two-thirds of the brass as can be obtained from the bearings of either of beforementioned patents.

Having thus described my invention, I claim as new and desire to secu re by Letters Patent 1. In a car-axle bearing, the combination, with the flat key fitting into the casing provided with a central aperture, of an in termediate plate held on the under side of the said key and the circularoffset fitting into the aperture formed in the said key, substantially as described.

2. In a car-axle bearing, the combination of a flat key fitting into the casing, a central aperture formed therein, an intermediate plate on the under side of the said flat key and with a semi-cylindrical concave bearing on the under side, and downwardly extending flanges formed on the side of said plate, and an axlebrass fitted between said flanges and provided with a semi-cylindrical convex bearing on its upper side, substantially as described.

3. In a car-axle bearing, the combination of a flat key fitted in the casing, a central aperture formed therein, an intermediate plate bearing against the under side of the key and provided with a eireularoflfset fitting into the opening in the key, having on its under side a semi-cylimlrical concave recess, downwardly-extending flanges, and an axlebrass having its bearing on the bottom of the intermediate plate and provided on its upper side with a semi-cylindrical convex surface and arranged within the do\vnwardly-extend in g flanges, substantially as described.

4. In a car-axle bearing, the combination, with the box or casing, of a key fitted in the casi ng and provided with a central opening, an intermediate plate bearing against the bottom of the key and having a circular hub fitting within the aperture formed in the key, the said intermediate plate being provided with an oil-hole and the semi-cylindrical concave under surface, and an axle-brass fitted to bear against the under side of the intermediate plate and provided with a central conical oila iiertui'e, substantially as described.
